class_docstr: Perspective API predicts the perceived impact a comment may have on a conversation by evaluating that comment
  across a range of emotional concepts, called attributes. When you send a request to the API, you’ll request the
  specific attributes you want to receive scores for.
  
  The API is hosted on Google Cloud Platform.
